Can you access the fault history in an ATS46 softstart using ModBus?

Issue: Can you access the fault history in an ATS46 softstart using ModBus?
Product Line: ATS46
Environment: All
Cause: N/A
Resolution: from the Global Help desk;
``You can access by ModBus with W4090 (from 1 to 4) for the fault number, the value is in W4069 and W4091 is used by the ATS to Recall the fault.``

What I think this means is that if you put a value of 1 in word 4090, the most recent fault will be reported in W4091. If you put a 2 in 4090, you will read the next oldest fault in 4091. 4090 is used as a pointer, and 4091 is used to display the value that is pointed to.

Add PM8000 Driver to ION Enterprise 6.0.1 or SPM 7.0.1

User cannot find PM8000 series in the device type drop down field when adding a new device in Management Console

PM8000 series
ION Enterprise 6.0 SP1
StruxureWare Power Monitoring (SPM) 7.0.1

A device driver is needed in order to correctly add the PM8000 to the system. This PM8000 series driver is compatible with ION Enterprise 6.0 SP1 and SPM7.0.1.

*Warning: Irreparable database damage can occur. This procedure should only be performed by users familiar with SQL Server Management Studio. Databases should be backed up prior to performing this procedure.*

Download the PM8000 series driver from the attachments or from Box at the following location:

The second line of the query may indicate a failure; however, the query will still add the device driver . 

It may be required to modify the PM8000.sql file to match the categories of DeviceType (first block of code) if the query continues to fail. Ensure the columns are listed and a value for each are specified in the 'SELECT' row, even if the value is set to null. Execute the query.
INSERT INTO DeviceType (Type, DisplayName, TreeFile, MapFile, EthernetSupport, SecurityModules, UsesFlashFile, IONBufferSize_bytes, TranslatorID, UnsolicitedTickPeriod_ms) 
SELECT '8000', 'PM8000', null, null, 2, 16, 1, 4096, [ID], 0 FROM Translator WHERE Name = 'ION'; 

When successful, the device type should be available in the drop down list in Management Console.

Starting Register number in Modbus Read functions

Goals and Symptoms

When performing Modbus read commands, it is important to apply the right starting register address in the read function. Otherwise, the wrong register will be accessed from the meter, giving unexpected data for the meter parameter being read.

  • Meter is functioning as expected. The front panel values for voltages and currents are within expected ranges for the system being monitored. However, modbus read functions from a master station (e.g. a PLC) give values that do not correspond to the front panel values.

Facts and Changes

Modbus, modbus rtu, function read, modbus map, holding register, staring register, function 03, modbus read packet

Causes and Fixes

One probable cause would be that, the modbus function read command is not pointing to the right registers. The modbus protocol requires an offset to be introduced in the starting register address when reading the slaves register.


When reading the meter parameters, the Master must send the device a Read Holding Registers packet. This packet must specify a start register and the number of registers to read. When the function read is received, the slave responds with a packet containing the registers in the range defined in the read request.

However, consider the 3710 Modbus map, which states that according to the MODBUS protocol, in response to a request for address 4xxxx, the master reads register xxxx-1 from the slave (3710). For example, a request for register 40011 returns register 10 from the slave.

What does the above statement mean? Why is an offset required?

Holding registers, by default, are defined the 4xxxx range, the first holding register staring at 40001. The starting register in the read packet is, on the other hand, numbered from zero. Hence, the start register zero automatically points to holding register 40001, starting register one points to holding register 40002, etc. The fact that the first holding register is 40001 and not 40000 explains the offset that needs to be introduced in the starting register number.

Hence, considering the 3710 Modbus Map statement, if the Master needs to read register 40011, then the corresponding starting register that needs to be put in the read function would be 10 (0A hex) since register 40011 is the register 10 from the first holding register, 40001:
40001 > Start register 0
40002 > Start register 1
40003 > Start register 2
40004 > Start register 3
40005 > Start register 4
40006 > Start register 5
40007 > Start register 6
40008 > Start register 7
40009 > Start register 8
40010 > Start register 9
40011 > Start register 10

The Modbus Read Request Packet for a master reading 3 registers from a slave with unit ID 100 (64 Hex) and for starting register of 40011 should be:

Slave ID
Start Register (40011)
# of Registers
CRC Checksum

To summarize, when looking at a modbus map, the starting register number to be used in the read function:

Start Register = Modbus Register 40001.
